Detect data in tables of roughly the same structure
Assuming all of the tables will be oriented in similar ways (label and value running horizontally) and that all writing will be printed rather than handwritten, one solution method would be to use an image segmentation method such as edge detection to segregate these horizontal (label, value) pairs and then use a library like Tesseract for OCR.
There are many types of image segmentation methods that may all have value, but if my assumption holds regarding the neat, structured nature of the tables, then I think simple edge detection methods could be sufficient.
